Establish basic UI tests with playwright

[alexcottner]

Our long term goal is to create comprehensive UI tests with playwright. But let's establish some good patterns and basic tests to get things rolling.

1. Test setup, create required data for tests
   1. Create admin account
   2. Create a test user account
2. Create a test bucket with the admin account
3. Grant the test user the ability to create collections in the test bucket
4. Create a test collection with the user account
5. Create a test record with the user account

Might be canceling this since we are moving our gatekeeper tests into another repo.
